To @ZZ whom it may concern.-

Be it known that I, HENRY STONE, a citizen of the United States,residing at Irvington, in the county of Essex and State of New Jersey,have invented certain new and useful Improvements in Lids or Covers forChamber-Pails and other Vessels, and I do hereby declare the following'to be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference v being had to the accompanying drawings, and vto letters of reference marked thereon, which form a part of thisspeciiication.

This invention relates more especially to certain peculiarities in theconstruction of lids or covers for chamber-pails and other vessels,whereby said vessels are rendered air and water tight when said coversare adjusted thereon, the object being to overcome certain diflicultiesand objections heretofore existing in respect to covers of thischaracter, and to accomplish better results at a less cost.

The invention consists in the peculiar combinations and arrangements ofthe several parts, as will be hereinafter set forth, and iinallyembodied in the claim.

In the drawings, in which similar letters of reference indicatecorresponding parts in each of the several figures, Figure l is aperspective view, partially in section, of a cover embodying myimprovements, and Figs. 2 and 3 are transverse sections of the same inconnection with a chamber-pail or commode,illus trating its operationwhen applied thereto.

In carrying out my invention I construct the top andthe bottom of thecover in separate parts capable of amovement toward and from each other,the object of which will be hereinafter set forth.

The central portion of the top plate, A, is

depressed or sunken, and is provided with two inclined ledges orprojections, b b, a perforation through the center, and a projectingrim, d, all as clearly shown in the several figures of the drawings.

The bottom plate, B, is provided with an upwardly projecting ilange, e,a projecting rim, c, and a central perforation corresponding with thatin the plateA.

The handle is composed of a knob or nger-piece, g, and cross-bar j, bywhich to manipulate the lid or cover. A shank, 7i, passing through saidhandle and through both the top and bottom plates, is held in positionby means of a nut; or it may be riveted or soldered to the bottom plate,as indicated in the drawings. An annular groove is formed by theconjunction of the two plates A and B, and is supplied with a rubberband, Z, fitting snugly and tightly therein, the normal tendency ofwhich is to press the top and bottom plates apart to their fullestextent, in which position the rubber band will lie smoothly and evenlyin said groove between the projecting rims c and d, as indicated in Eig.2, and the cross-bar j of the handle will lie in the depressionbetweenthe inclines in the top plate, as indicated in the same iigure. i

The operation of the device is as follows: The cover being shut downinto the top or mouth of the vessel, (into which it should t easily butsnugly,) the handle, or rather the cross-bar of the handle, is turned soas to bring saidcross-bar j into engagement with the inclines b b;which, as said cross-bar is turned upon the shank, forces the top andbottom plates together or toward each other, the result of which is tobring a pressure upon the edges of the rubber band, thereby causing thelatter to bulge outward, and to thus press against the inside of thevessel, or preferably into a recess, s, formed on the inside of thevessel, as indicated in Figs. l and 3, thereby holding the lid or coverin position, and forming an air-tight and a watertight joint, as will,be manifest. By reversing the movement of the cross-bar the cover may beremoved. Additional means for securing or fastening the cover may beemployed, if desired.
